I need a book on critical rhinking and problem solving
There should be books on both of those topics in our two biggest electronic book collections.
On the Online Library page, click on the Find Books button. A new page will open with links to the electronic book collections.
The two big ones are 'ebrary' and 'EBSCO eBooks.' Click on the link for one of them and put your terms in the search box.
There should be several books listed no matter which collection you choose.
I hope that gets you started!
